    摘要： The present invention is a method to produce an unsaturated carboxylic acid which includes the steps of: providing an epoxy compound; contacting the epoxy compound with carbon monoxide in the presence of a catalytically effective amount of a catalyst system comprising tin and cobalt under conditions effective for carbonylation of the epoxy; and recovering a .alpha.-.beta. unsaturated carboxylic acid product. The preferred epoxy is ethylene oxide which is reacted to acrylic acid by the method of the present invention.

    摘要： Disclosed is an improved catalyst system and process for preparing aliphatic carbonyl compounds such as aliphatic carboxylic acids, alkyl esters of aliphatic carboxylic acids and anhydrides of aliphatic carboxylic acids by carbonylating olefins in the presence of a catalyst system comprising (1) a first component selected from at least one Group 6 metal, i.e., chromium, molybdenum, and/or tungsten and (2) a second component selected from at least one of certain halides and tertiary and quaternary compounds of a Group 15 element, i.e., nitrogen, phosphorus and/or arsenic, and (3) as a third component, a polar, aprotic solvent. The process employing the improved catalyst system is carried out under carbonylating conditions of pressure and temperature discussed herein. The process constitutes and improvement over known processes since it can be carried out at moderate carbonylation conditions without the necessity of using an expensive noble metal catalyst, volatile, toxic materials such as nickel tetracarbonyl, formic acid or a formate ester. Further, the addition of a polar, aprotic solvent to the catalyst system significantly increases, or accelerates, the rate at which the carbonylation takes place.

    摘要： Methacrylic acid is produced by the oxidative carbonylation of propylene by contacting propylene, oxygen and carbon monoxide in the presence of a Group VIII noble metal catalyst containing a redox agent and an alkali metal acetate. Preferably the oxidation is performed in liquid phase comprising a low molecular weight fatty acid as the solvent. In a typical embodiment, the Group VIII noble metal concentration is from 0.001 to 1.0 molar, the concentration of the redox metal is from 0.05 to 0.5 molar, the concentration of the halide anion is from 0.1 to 0.5 molar and the carbon monoxide partial pressure is from 10 to about 70 percent of the total pressure which is from about 300 to 3,000 p.s.i.g. Under these conditions a substantial portion of the product comprises the desired methacrylic acid.
